UNITED STATES ROBERT H. HASSLER, OF INDIANAPOLIS, INDIANA.

SHOCK-ABSORBER MOUNTING FOR VEHICLES.

Application filed June 5,

T all whom it may concern:

Be it known that I, .Ronnnr H. HASSLER, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Shock-AbsorberMountings for Vehicles, of which the following is a specification.

The present invention relates generally to improvementsin shockabsorbing devices for motor vehicles and is more particularly directedto the provision of means for mounting shock absorbers on vehicles, andone of the objects of the invention is to improve the efficiency of theshock absorbers by reason of the peculiar and novel form of mounting.Another object of the invention is to provide means by which a standardform of shock absorbing device may be attached. to miscellaneousVehicles of different sizes and shapes and still retain the best workingconditions for the device.

A further object of the invention is to provide means for mounting andconnecting shock absorbers which are capable of being shifted to variousangles and positions on the vehicle, for the purpose of clearing thenumerous obstructions encountered when making installations, and stillmaintain an approximately vertical line of connection between the upperand lower ends of the straps or rods that are used to transmit movementto the shock absorber.

With these and other objects in view, the invention consists of theconstruction, combination, and arrangement of parts hereinafter morefully described and claimed, and illustrated in the accompanyingdrawings, in which like characters of reference indicate like partsthroughout the several figures, of WlllCl1- Figure 1is a fragmentaryplan view of a vehicle chassis illustrating the employment of myinvention. Fig. 2 is a side elevation partly in section and taken on theline 2--2 in Fig. 3. Fig. 3 is another fragmentary plan view showing theimproved system of mounting a shock absorber on a vehicle chassis of adifferently constructed type. Fig. 4 is an end elevation of the framesupport in which a fragment of the shock absorber is shown pivotallymounted and'is taken on the line 4L-4 of Fig. 3. Fig. 5 is a crosssection on the line 5-5 in Fig. 9. and illustrates'a side view of theswivel type axle bracket. Fig. 6 is a plan view of the axle 1922. SerialNo. 565,814.

bracket partly in section taken on the line 6-6 in Fig. 5. Fig. 7 is aplan view of the swivel bolt. Fig. 8 is a front view of the axle andaxle bracket, and illustrates an inclined position of attachment of thebracket to the axle, and is an approximate front view of Fig. 1 showinga fragment only. Fig. 9 is a partial front iew of the axle andattachment shown in Fig. 3, and shows the axle bracket dotted in avertical position. Fig. 10 is a section of the shock absorber taken onthe line 10-1O of Fig. 2.

Referring to the drawings, 3 is the main vehicle leaf spring which issecured intermediate its ends to the vehicle axle 5. 7 is the vehicleframe member, and9 the vehicle wheel. The outer end of the vehiclespring 3 is pivoted to the usual born or curved end of the frame 7, andthe opposite end of spring 3 is shackled to an intermediate portion ofthe frame member 7 in the usual manner. The foregoing described partsare or may be of any well known or desired type.

The improved system for mounting shock absorbers on vehicles comprises aframe support 11 provided with extensions or ears 11.

and 11". formed for pivot-ally attaching any desirable type of shockabsorber or damping device; the frame support 11 being attached to theframe by means of bolt 15. For con Venience of illustration, 1 haveshown a fric tion type shock absorber provided with an attaching ear 19for pivotally attaching the shock absorber to the frame support 11, f orwhich a pivot bolt 21 and nut 22 are employed.

This friction type shock absorber contemplates the use of a centersupport or hub member 19 which contains a flanged por tion or diskcontainer 19, from the outer periphery of which project a plurality ofoutturned lips or keys 19". is a cylindrical bush pressed into thecentral hollow portion of the hub member 19 forming a 'jour nal orbearing. Into disk container 19 is pressed and securely held fromrotating, the friction disk 16. Q lis a second disk container or flange,containing on its periphcry a plurality of lips or keys 24 which fitloosely between the keys 19 on disk container 19 thereby permitting anaxial movement of the disk 24. with relation to the disk container 19*,but look one with the other circumferentially. 26 is a second frictiondisk securely pressed into container 24 and,

Under these conditions, I set the shock absorber7" body 17 at an anglewith the frame as shown by the dotted line E, inFig. 1, and secure it1in; this posit-iontby clamp bolt 21.
